Question

Solve it pls.

Air at free-stream velocity of 8 m/s flows over a thin flat plate of length 5 m and width 1 m. A lamirar boundary layer develops from the leading edge of the flat plate. At Re, = 800 000, the boundary layer becomes a turbulent boundary layer where x is the distance from the leading edge. pair = 1.2 kg/m', lair = 1.8 x 105 kg/m.s (a) Estimate the length of the laminar boundary layer. (b) Estimate the drag force due the laminar boundary layer on one side of the flat plate. (c) Wall shear stress atr= 5 m.
